Worth prefers that every player chooses their strings freely. You may notice that they are classified by two lengths - 46 and 63 inches - which is the total strings length. Some players prefer BL for their tenor ukes while on the other hand, players choose CF for their soprano or concert ukes. The longer the instrument, the higher the tension will be with the same string set. For starters, you can try the BT or CT, depending on your tone choice. From there if you want a higher tension, try CH. If you want a lighter touch, try CM. Experimenting is the only way to find what is right for your exact preference.
